Question

why hydrogen not get proper place in periodic table?

Answer 1

• there have from time to time been discussions about the position of hydrogen in the periodic table. It has been quite usual to show it in two positions, both above the alkali metals and above the halogens. ... Although its electron configuration (ls1) links it to the alkali metals, its analogy with the halogens is strong.
• Hydrogen is a nonmetal and is placed above group in the periodic table because it has ns1 electron configuration like the alkali metals. However, it varies greatly from the alkali metals as it forms cations (H+) more reluctantly than the other alkali metals. ... However, hydrogen is very different from the halogens.

Answer 2

The assignment of hydrogen to the alkali-metal family of elements, because it has one electron in its outer shell, is noless absurd than it would be toplace helium over beryl- lium because it has two outer electrons. ... It is even less metallic than oxygen and most of the halogens. ...
